Specicaton of Letters Patent No. 406, dated September 25, 1837.

To all 'whom it may concern `Be it known that I, SAMUEL RUST, of the city of New York, county and State of New York, have invented a new and useful Improvement in Samuel Rusts Patent Lamp for Lighting` Houses' and other Places,V (which patent was granted unto the said SAMUEL RUST, dated the sixth day of October, 1835, and has been since sold to William Rowe, of Fishkill, Dutchess county, State of New York, and that the following isa full and correct description of said improvements as invented or improved by me rPhe nature of my invention or improvement in the above said patent lamp, consists of the insertion of the roller of said lamp (which regulates the wick) into that part designated as the stopple of the lamp, in place of inserting it into the tube or socket above the stopple or into the top of the lamp at the bottom of a short tube or socket as in said patent which stopple is particularly adapted for said roller. )Vhereas the stopple in said patent lamp, is made the same as the usual stopple in other common lamps (and the roller inserted into the tube or socket above the stopple 7) I make it with a rim, raise or projection, about three tenths of an inch (more or less) above theJ part which enters into the lamp and insert said roller at o-r into this rim, raise, or projection, and through or at the side of the tube or socket which receives the wick (see A Fignres l and 2 which roller, when inserted into said stopple, is also used at the bottom of the short tube or socket (see B C, Figs. 3 and 4t) (in place of using it insertedl into the top of the lamp as in said patent) by placing a plate or bearing in and across the stopple opposite and parallel with p the roller (see D, Fig. 4) and so close to the roller as to just leave room for the wick to pass between the plate or bearing and the roller, with a gentle pressure, so that when the roller is turned it moves the wick up or down as required. This stopple is made thick at the part where the roller enters and forms an excellent support to the roller and likewise, the roller inserted into the stopple as above described, is better on account of taking the stopple out to cleanse the inside of the lamp, than when inserted into the top of the lamp and, also, the roller is easier made movable to take out and put in at pleasure than when inserted into the tube above the stopple which may be done by a catch, slide or pin, pressing down through the top of the stopple and into a groove or neck in the end of the roller.

For further illustration of the whole, the

annexed drawings are referred to with the Y explanations, as making a part of this specification.

My invention or improvement and what /I now claim and desire to secure by Letters in any other way or mannerthat is essen-V tially the same, combined as above set forth.

Witness my hand this twenty-sixth day of April, A. D. one thousand eight hundred and thirty-seven.
